Description

Fabric, manufacturing method thereof, and fiber product containing the fabric

The present invention relates to a fabric, a manufacturing method thereof, and fiber products containing the fabric.

Generally speaking, clothing is manufactured by cutting and sewing cloth. The opening of clothing usually folds the cut end edge of the fabric and sews it, or wraps it with patchwork such as chain cloth and sews it, so as to implement fray prevention around the end edge. However, it takes considerable sewing time to prevent the fraying of the cut edge of the fabric or the cut edge of the opening, and the cut edge of underwear, etc. appears in the outer garment step, which damages the fashion, or the seam touches the skin However, the wearing feeling is impaired. Therefore, it is required to improve the underwear or sportswear, which is in direct contact with the skin.

In order to meet the above requirements, for example, the following patent document 1 proposes a clothing material that has a 1×1 Tricot structure for at least non-elastic yarns, and the elastic yarns include a stretchable warp knitted fabric with loop structure to compare The direction is 3 degrees or more and 177 degrees or less for cutting. In the cut state, the edge without edge treatment becomes the edge of the cloth. In addition, the following Patent Document 2 proposes a cloth with a frayed pattern, which includes a knitted fabric having a fray-proof function by knitting hot melt elastic yarn and other yarns by adding yarn knitting. However, these technologies are based on woven fabrics, and do not disclose any fabrics in a fringe-like pattern without edge treatment or clothing containing the fabrics.

In recent years, due to the diversification of fashion, this type of clothing with loose edges is not only used in underwear or sportswear that directly contacts the skin, but also in shirts or slacks, women’s bottoms, jackets, coats, etc. In so-called external applications where fabrics are used more frequently, the requirements have also increased. In addition, recently, even in external use, in terms of wearing comfort, a fabric with moderate stretchability is required. In Patent Document 3 below, regarding the fray prevention of fabrics, a fabric and a manufacturing method thereof are disclosed. The fabric is used for fray prevention of unit cushion fabrics such as coasters or table cloths. It melts. However, since hot-melt yarns are only used for weft yarns, the fabric's warp resistance is not sufficient. In addition, since the hot-melt yarn is only used in the cutting part of the fabric, the area that can be cut is limited. If it is used in the state of cutting at various angles, the yarn will be loose, so it is not suitable for use in clothing. In addition, the following patent document 4 discloses a method for manufacturing mesh style fabrics, which aims to prevent the twisting of the pattern of the mesh style fabrics by comparing hot melt fibers and dissolved fibers dissolved in water or solvents. The fabric is subjected to heat treatment, and then a part of the dissolved fibers is dissolved and removed with water or a solvent to prevent the texture of the fabric from twisting. However, since the hot-melt fiber is only arranged around the holes that make up the mesh, if it is used in a state where it is cut at various angles, the yarn will loosen and it cannot be used in clothing. In addition, since the fibers constituting the mesh-style fabric include fibers having a melting point higher than that of the hot-melt fibers, the stretchability is insufficient, and it is not suitable for clothes that require comfortable wearing.
